CLEANING' DEVICE.

Specification of Letters Patent.

To aZZ whom it may concern: w

Be it known thatV I, PASCAL J SHAMPAY, a citizen of the United States, re'siding at Chicago, in the county -of Cook, Illinois, have injvented certainnew and useful Impi'ovements in Cleaning which tlie following is a specification.

This invention relates to a device for cleaning carpets, rugs and the like, and more particularly to a scouring or cleaning brush for such a machine, and tlie principal object of the invention is to dispose tlie bristles of the. that the cleaning Aliquid will be directed by the bristles, as the' brush rotates, toward the longitudinal center of the brush, or at least away from the ends brush iii such a manner thereof.

A further object of the invention is to provide a brush of this kind in connectioii with an appropriate cleaning fiu'id receptacle so .arranged that the surplus cleaning fluid will not be discharged fromthe end of the receptacle, ber upon whicli the article to supported.

For the attainnient of these ends andpthe accomplishment of other objects, as will ap-` pear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts generally shown in 'the accompanying drawing and more appended be cleaned is particnlai'lyv pointed out in the claims.V p i In the di'awings,- Figure 1 is a sectional view consti'ucted ples of my invention; w I w V g Fig. 2 is a detail longitudinal section of a portion of the device, showing the relation of the parts; Fig. 3 is a viewl of a brush constructe'd'in accordance with the principles of my invention, and comprising lspiral 'rows of bristles the ends of directed towai'd each other from the brush and meeting intermediate the ends,

Fig. 4 is a view to illu's trate the ;use of the device in connection with an article which is less in width thanv the width of the cleaning device. Q w In cleaning devices of this kind, it is'customaryto employ cleaning brushes in which State of w Devices, of

between it and the .movab'le mein- 'is disposed for cleaning.

i'otates, and cleansing of a device in accoi'dance with the ,princicleaning the bristles are ai'ranged in rows which are disposed'ai'ouiid'the brush in applane transverse to the axis thereof'. The brush of the present invention differs from* this, the 'bristles 'ai'earranged in spiral rows eX- tending from the ends of the brush in opposite dii'ections to a point intermediate the ends of the brush. These cleaning' brushes being disposed in a cleaning fiuid receptacle, tend to discharge the'surplus fluid from the ends of the receptacle between the receptacle and the inovable member to which the article to be cleaned is attached. siderable cleaning fiuid is discharged from the 'receptacle and goes to waste.

In this invention a cleaning brusli 0 vcom- In this way, conprises a core 7, inountedby means of a shaftl 8 in a 'cleaning fluid receptacle 9. One end of the sliaft'S which extends'through the end of the receptacle 9 carries a gear 10, or other suitable means, by means of which the brush may be rotated. Disposed above the receptacle 9 is a rotatable drum 11 or other movable support, upon which an article 12 The larticle is drawn by the drum against the brush as it fluid is applied to the outer face of the article to be cleaned, by means of theV brush. The cleaning fiuid receptacleis'formed on one side with an eX- l'tension 13, having a bottom inclined to the receptacle proper.

' t is provided with a scraper or wipei' 13' 'on the other side, pref- V ei'ably made of 'i'ubber oi'- other flexible inatei'ial, for engaging the article cleaned after it leaves the brush to wipe the cleaning liquid from the'iarticle and to prevent the fluid from eXuding or being tlirown from the receptacle'). Disposed at the upper end of the extension is a cleaning'fiuid discharge pipe 1%, with discharge openings '15, 'each controlled by means of a valve on a.

valve lever 16 having'a roller`17 at one end thei'eof adapted to be engaged' by the article to be cleaned,' to'open thevalve. These leversY 16 :are disposed atiiitervals along the pipe 14, and only the levers'v actually engaged by .the article to be cleaned are operated, so that therejwillbe no surplus fluid dischargedinto the receptacle 9.' i

The brush proper comprises a plurality of rows of bristles 18, extending spirally from both ends of the brush in opposit'e directions Patented Feb. 27, 1917. Application filed .Tune 19, 1914. Serial No. 846,060. i

in that Lam around the brush, until they meet at a point intermediate of the ends, preferably at the longitudnal center of the brush. The effect of these rows of bristles is that of a double screw, so that, when the brush is rotated in the proper direction the rows of bristles tend to force the Cleaning` fiuid away from the ends of the brush and toward the center thereof. The effect of this is to direct the cleaning fluid to the center and to prevent it from exuding from the ends of the receptacle 9, to as great an eXtent as possible. lt is impossible to fill the space between the drum 11 and the ends of the receptacle, as shown more clearly in Fig. 2, and some outlet is desired for the excess of cleaning fluid in the receptacle. 'owever, this brush tends to direct cleaning;` fiuid toward the center, and when an article of less width than the drum ll is applied thereto it is preferably disposed at about the center of'the drum, so that the bristles at the center of the brush will engage the article to be cleaned, and only the valves 16 which are engaged by the article to be cleaned will be opened, thus directing the Cleaning fluid to the brush adjacent the center thereof, approximately the width of the article to be cleaned. rllhe tendency of the rot'ation of the brush with the oppositely disposed spiral rows of bristles 1s to keep the Cleaning fluid in the center, and therefore the maximum efliciency of the brush and in the use of the Cleaning fluid will be obtained, and only when the receptacle 9 is full, will the surplus be discharged from the ends.

It should be noted that the brush substantially fills the receptacle in which it operates, or at least is in close proximity to the surface thereof, although this need not necessarily be the case, but the action of the brush is to churn the cleansing` fluid, which ordinarily is of soapy consistency, so that a great amount of foam is formed, which fills the receptacle very rapidly and which of course, if means is not provided, tends to escape rapidly from the receptacle at the ends thereof. The disposition of the bristles of the brush in this case is such as to counteract and minimize the tendency of the foam and cleansing material to escape from the ends, to as great an eXtent as possible.

I claim:

1. In av carpet cleaning` device, a rotary brush having spiral rows of bristles extending` in opposite directions from the ends and meeting` at points intermediate the ends, and means to feed cleansing,` fluid to the brush fon the width only of the carpet to be cleaned, whereby the brush in rotating tends to confine the cleansing fluid only to the width of the carpet to be cleaned.
